Who tests the useless survey? Everyone with regression tests. Like dude, everything you talk about has been written “in blood” from years of hosting production systems. If the useless survey is needed, then write a test for it, or a testcase to manually try it. Don’t just upgrade, see that the app is up and push to prod, that’s not testing, that’s asking for trouble.
2% yearly reductions most likely. Some shitty companies fire a small percent of their staff and hire new people - especially when someone has been there long and isn’t irreplaceable.
